ings next to each other, so for instance short and long veins mayappear. in numerous shapes and forms at the same time.

It is the object ofthe presentinvention to enable the production of suchcontinuous wood-grains also in linoleum.

The present invention is 'based 9n the known method of making blocks oflinoleum composition by'piling slightly rolled plates of granularlinoleum composition on each other and cutting the final linoleum platestransversely ofl this block. a

According to the present invention the linoleum composition plates whichare to be piled up so as to form a block are not simply I rolledhomogeneously of so-called granitoid composition, as the plates cuttransversely from such blocks are extremely homogeneous and donot showany great variation in the patterns of the veins, but said linoleumcomposition plates tobe piled to a block are rolled of severaldifferently treated linoleum compositions, namely of granularcomposition, composition molded in the shape of sausages or similarbodies and of bodies consisting or two or more compositions of differentcolor prepared in known manner according to the German Patent No.171,111, whereby the first or last of these compositions may also beomitted. The several differently prepared compositions are not rolledtogether all'at the same time, but first one of the differently preparedcompositions is slightly rolled between two rollers, then the secondprepared composition is slightly rolled over such first composition andoverthese two a third prepared composition is slightly rolled. p

The accompanying drawing diagrammatically exemplifies a constructionalform of an arrangement for carrying out the method forming the'subjectmatter of the present invention.

a is a main roller, around which are arranged the secondary rollers b, cand cl. Into the hopper (Z is filled say a granular linoleum compositionand rolled slightly between the main roller a and the secondary roller6.

Into the second hopper is filled a linoleum composition consisting ofself colored composition sausages or slmilar'bodies the various selfcolored sausages or the like differ-- ing in color between each other,which sausages or the like are prepared in known manner of two or morecompositions of different colors or tints. Between the secondary roller0 and the main roller 0: these sausages or the like will bevrolled to asecond layer over the first layer rolled between the roller 6 and themain roller a. Into the third hopper h is filled a composition which maycons1st say of two or more granular compositions of difierent colors soloosely connected with each other, that the several compositions are notyet mixed up or incorporated in each' other according to German PatentNo. 171,111, whereupon this third charge is rolled between the roller (Zand the main roller a to a third layer on top of the first roller. Ifthe thus obtained combination bands are piled in known manner to ablock, and plates are transversely cut off this block, these plates willshow the desired variations in the grain with long and short designs.These designs willbe chiefly produced by the slightly preparedcomposition sausages or the like employed in making the com: poundbands, which sausages or bodies are more or less deeply embedded duringthe rolling operations into the previously but slightly rolledcomposition layers, and will therewith displace the respective material.

Compound bands '2' may also be made of only two of the hereinbeforementioned compositions, of a granular composition and a which thedifferently treated compositions are employed in making the compoundbands z; so for instance the lowermost layer may be made of sausageshaped bodies, the next one of granular composition or in any otherseries. Instead of self-colored granular composition also a mixture ofdifierent colors or tints may be employed.

I claim:

'1. The herein described method of making plates of linoleumcomposition, consisting in rolling several differently prepared linoleumcompositions of'ordina-ry granules successively on top of oneanother.

2. The herein described method of making plates of linoleum composition,consisting in rolling several differently prepared linoleum compositionsof ordinary granules successively on top of one another, and forming oneof said compositions prior to its being rolled into the shape of loosesausage like bodies."

3. The herein described method of making plates of linoleum composition,consisting in rolling several differently prepared linoleum compositionsof ordinary granules succesof said compositions prior to its beingrolled in the shape of loose sausage like bodies, and in forming anotherof said compositions prior to its being rolled of differently colored 25loosely connected masses.

In. testimony whereof I have aflixed my signature in presence of twowitnesses.
